Tony Hawk has spent a lifetime shredding, and now he’s hoping to give that gift back through his work in the Tony Hawk Foundation.

His charitable organization’s latest project is called Boards + Bands, which is the brainchild of Hawk and his friend (and Grammy-winning musician) Ben Harper. The idea is simple: A bunch of the biggest skateboarders in the world have donated actual boards that they’ve ridden, and those boards were then sent to a bunch of legendary musicians for some turned-to-11 customization.

The boards are currently up for auction, with the proceeds going to building public skateparks for at-risk kids in low-income communities. The decks feature hand-written lyrics by the likes of Harper, Paul McCartney, Metallica’s James Hetfield, Bob Dylan, the late Adam Yauch, Jimmy Cliff, and Tom Petty.

McCartney’s board features some lines from “Blackbird,” while Yauch spread the lyrics to the appropriately zen Beastie Boys track “Bodhisattva Vow” across three different boards. The decks are also currently on display at the Grammy Museum in Los Angeles.
